Underground Climate Change: Shifting Ground in Cities

“Underground climate change threatens city stability as urban ground deformation due to heat absorption causes building cracks.”

Scientists have recently discovered a new and concerning phenomenon known as underground climate change. This phenomenon is linked to the shifting ground beneath urban areas and has significant implications for the stability and functionality of cities.

Cities are already known for their heat island effect, where they absorb and release heat differently than rural areas. However, it is now understood that cities not only release heat into the air but also into the ground. As the ground heats up, it deforms, causing excessive movement and even cracking of building foundations and the surrounding ground.

A study conducted by scientists at Northwestern University in Chicago revealed these findings. Data collected from sensors placed in basements, subway tunnels, underground parking garages, and subsurface streets supported the conclusions. The researchers expect these issues to persist for years to come.

While underground climate change may not directly pose a safety risk to individuals, it can significantly impact the day-to-day operations of foundation systems and civil infrastructure. Many downtown foundations are experiencing unwanted settlement, leading to a gradual sinking effect. This highlights that living in a sinking city is not limited to places like Venice; cities worldwide can face similar subsidence issues due to different causes.

This video from Northwestern University shows how underground climate change can affect the infrastructure within cities.

It is important to understand and address underground climate change in urban planning and infrastructure design to ensure the long-term stability and functionality of cities. Unfortunately, no existing civil structure or infrastructure is designed to withstand the ground deformations caused by this phenomenon. Increased awareness, research, and mitigation efforts are necessary to tackle this silent hazard and protect urban environments from its consequences.

The study, published in Nature Communications Engineering, emphasizes the need for further research and consideration of underground climate change in urban development. By addressing this issue, cities can better prepare for the long-term effects and ensure the resilience of their infrastructure in the face of changing climatic conditions.

Breast Cancer Awareness Month: Taking Action

Make a difference during Breast Cancer Awareness Month by taking action, supporting early detection, and accessing resources.

Published

on

Breast Cancer Awareness Month (BCAM) is a significant time when pink ribbons symbolize the fight against breast cancer. However, it’s crucial to understand that awareness alone is not enough. This October, let’s go beyond awareness and take action.



A breast cancer diagnosis can be overwhelming, which is why initiatives like the NBCF Patient Navigation Program exist—to ensure that no one battles breast cancer alone. Early detection is key to successful outcomes, but many people may not know what signs and symptoms to look for. Thankfully, resources like NBCF’s “Most Asked Questions: Breast Cancer Signs & Symptoms” provide answers and guidance.

We can all make a difference during BCAM. Use your voice, passion, and financial support to ensure that every woman has access to critical screening, support, and care. By getting involved, getting screened, making a donation, or taking action, you can directly impact the lives of those affected by breast cancer.

Breast Cancer Awareness Month extends beyond awareness campaigns. In the United States, organizations like the National Football League incorporate pink into their activities, and even comic strip artists dedicate a day in October to raise awareness. Additionally, various walks and events raise funds for breast cancer programs, such as the iconic Race for the Cure, which began in October 1983.

Let’s make Breast Cancer Awareness Month a time of action, support, and empowerment. Together, we can make a difference and ensure that everyone facing breast cancer receives the care and resources they deserve.

United States Space Force: Protecting America’s Interests in Space

“Learn about the United States Space Force: its formation, purpose, and role in protecting national security and space assets.”

Published

on

The United States Space Force (USSF) is the newest branch of the U.S. Armed Forces, established to protect American interests in space. It was formed on December 20, 2019, when President Donald Trump signed the United States Space Force Act, making it the first new independent military service in over 70 years.

While the concept of a Space Force had been discussed since the 1950s, the need for a dedicated space-focused military branch became increasingly evident with the growing importance of space in national security and defense. The USSF operates under the Department of the Air Force, similar to how the Marine Corps operates under the Department of the Navy. It is led by the Secretary of the Air Force and its military heads are the Chief of Space Operations and the Vice Chief of Space Operations.

The Space Force’s primary purpose is to ensure the freedom of operation in space and protect U.S. space assets. It is responsible for organizing, training, and equipping space forces, which are then deployed to the unified combatant commands, particularly the United States Space Command. The Space Force operates various programs and systems, including GPS, the Space Fence, military satellite communications constellations, X-37B spaceplanes, the U.S. missile warning system, the U.S. space surveillance network, and the Satellite Control Network.



The USSF’s formation marked a significant recognition of the critical role space plays in national security, communication, and technological advancement. As the world becomes increasingly reliant on space-based assets for navigation, communication, and intelligence gathering, the Space Force aims to protect these capabilities, deter aggression, and maintain superiority in space.

By establishing the Space Force, the United States has demonstrated its commitment to safeguarding its interests in space and maintaining its position as a global leader in space capabilities. As technology continues to advance and more nations venture into space, the United States Space Force will play a vital role in ensuring the security and resilience of American assets in this final frontier.
